Landmark UN report warns sea levels will rise faster than projected by 2100

Cities from New York to Shanghai could see regular flooding, as sea levels rise faster than previously thought. Glaciers and ice sheets from the Himalayas to Antarctica are rapidly melting. And the fisheries that feed millions of people are shrinking. These are just some of the impacts that emissions of greenhouse gases have already triggered across the planet's oceans and frozen regions, according to a new landmark report from the United Nations' Intergovernmental Panel on Climate Change (IPCC).
More than 100 scientists from 36 countries worked on the report -- titled the Special Report on the Ocean and Cryosphere in a Changing Climate. It is the last of three special reports from the IPCC following last October's urgent report that showed the world may only have until 2030 to keep global warming below 1.5 degrees, and August's report on climate impacts to the planet's lands.
"This report is unique because for the first time ever, the IPCC has produced an in-depth report examining the furthest corners of the Earth -- from the highest mountains in remote polar regions to the deepest oceans," said Ko Barrett, vice chair of the IPCC. "We've found that even and especially in these places, human-caused climate change is evident."
